countreg: Count Data Regression

Regression models for count data, including negative binomial, zero-inflated, zero-truncated, and hurdle models. Drivers for combination with flexmix and mboost are also provided. Previously available functions for graphical goodness-of-fit assessment (rootograms etc.) are now provided in the 'topmodels' package on R-Forge.

Authors:Achim Zeileis [aut, cre], Christian Kleiber [aut], Thorsten Simon [ctb], Kevin Huynh [ctb]
